Hi Losingtheplot, I hope you find a solution. It is so frustrating that every med is at least one step back for each couple of steps forward.
Magnesium, people are suggesting, I agree, forgot about that.
Sometimes a couple of cocodamol at bedtime can ease my sleep in general, makes me more restful in my sleep.
Zinc is another important menopause mineral for the brain, take at a different time from magnesium, they affect each other's absorption somehow.
I tried lithium a while back too and while I've not bothered to get more I keep meaning to, I think that benefitted my calm too. I twitch more if I'm stressed, don't know if you do that too.
I hope you are sound asleep now
